Key result
Waist-to-height ratio outperforms waist-to-hip ratio for identifying metabolic syndrome in Bangladeshi physicians.
Why the study?
Bangladeshi doctors lead a sedentary and mentally stressful life with low physical exercise that predisposes them to metabolic syndrome. This study aimed to evaluate the predictive value of waist-hip ratio, waist-height ratio, TG, and HDL-C for metabolic syndrome in this population.
Do waist-hip ratio (WHR), waist-height ratio (WHtR), triacylglycerol (TAG), and HDL-C accurately predict metabolic syndrome in Bangladeshi doctors?

This study highlights a high prevalence (38.8%) of metabolic syndrome among Bangladeshi physicians and supports waist-to-height ratio (WHtR) as a superior anthropometric predictor compared to waist-to-hip ratio (WHR).
Metabolic syndrome (MS), a global epidemic, is a cluster of risk factors for CHD, T2DM, stroke and other various medical problems, which affects specially those who lead sedentary and stressful life. Among the health service providers of Bangladesh, doctors are very important group who leads sedentary and mentally stressful life with low physical exercise. The aim was to evaluate WHR (waist-hip ratio), WHtR (waist-height ratio) and TG, HDL-C for their predictive value of MS. In this cross-sectional study, by convenient and purposive sampling technique, 25-55 years aged 500 Bangladeshi doctors (male 334, female 166) were enrolled. The study was carried out in the Department of Biochemistry, BSMMU, Shahbag, Dhaka, Bangladesh. MS was diagnosed by modified NCEP ATP III criteria. Prevalence of MS was measured at 95% CI. Statistical significance was set at p<0.05. Prevalence of MS was found 38.8% in total study subjects; that in male and female was 24.6% and 14.2% respectively. Performance tests of predictors were done. WHR was the most sensitive (99.19% male & 98.59% female), TG was the most specific (94.79% male & 62.11% female) & accurate (78.1% male & 68.1% female) predictor. ROC curves of predictors were produced and all were found good (AUC>0.6) for their predictive value of MS; WHtR was revealed better than WHR as an index for MS (AUC 0.667 vs. 0.652 in male; 0.706 vs. 0.681 in female). It can be concluded, the prevalence of MS is very high among the doctors of Bangladesh; WHtR can be used as a good and relevant index for MS. Bangladesh J Med Biochem 2018; 11(1): 26-35

Baul et al. (2019) conducted a cross-sectional in Metabolic syndrome (n=500). Waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), triacylglycerol (TAG), and HDL-C was evaluated on Prevalence of metabolic syndrome (modified NCEP ATP III criteria) and diagnostic performance (AUC) of WHtR vs WHR (AUC 0.682 (WHtR total); AUC 0.667 vs 0.652 (WHtR vs WHR in males); AUC 0.706 vs 0.681 (WHtR vs WHR in females), 95% CI 0.6-0.7, p=.000). Waist-to-height ratio outperformed waist-to-hip ratio in predicting metabolic syndrome (AUC 0.667 vs 0.652 in males; 0.706 vs 0.681 in females) among Bangladeshi doctors with a 38.8% prevalence.
